side seams with non-metallic packing strips disposed so as to be bent or folded into the hooks interengaging to form the locked portion of the seams and to extend beyond said hooks and be included between the lapped portions of the seams. The provision of solderless side seams oi any form, and particularly those including non-metallic strip inserts of the character just mentioned, present problems when the open ends of formed container bodies are anged to prepare them for seaming operations incident to end closure applications subsequently ,to be effected because the angingdevices conventionally employed serve to spread and disrupt or distort the seams at the portions thereof extended beyond the interlocked side seam hooks, thereby rendering diiiicult and sometimes impossible eincient sealing of the containers. Another dim-A culty experienced in the anging of container bodies having this form oi side seam was that of so turning the anges that the seams formed in the ultimate sealing of the containers, and which included the flanges, would grip the seam at the extremity of the seam hook portions and vefficiently seal the seam at this danger point de- Void of solder and interlock. The present invention seeks to provide a novel container body flanging mechanism which will remedy the conditions and avoid the diiculties referred to.

The co-pending patent application'l Serial Number 371,974, hereinbefore referred to, discloses the particular solderless side seam includ-'- ing themen-metallic packing strip insert as well as the mechanism for applying the strip, and in that application disclosure reference is made to alcomplete body maker or three sections, namely, the section disclosed in that application and which includes the packingl strip applying mechanism, the double blank ejecting devices, and suitable means for-feeding the blanks and also for grain breaking the same after the usual custom, a second section comprising a standard form of body maker vfrom the machine composed of position.l of the blank notching mechanism on through the forming station, and a third section comprising a flanging mechanism for langing `the ends ofthe formed container bodies immediately after they are formed. AThis third machine section constitutes the subject matter of the present invention.

v Anfobject of the invention is to provide a machine for iianging container bodies of the characterA stated and embodying a continuously rotated rotor -having a plurality of can body re' ceiving and end confining pockets therein, means for feeding formed containers one by one into lsaid pockets, and reciprocable iianging heads movable simultaneously toward or from each vother and effective to engage in container body ends confined in said pockets and ange said ends without improperly spreading or distorting the side seams at said ends.

Another object of the invention is to provide a machine of the character stated in which the container receiving and confining pockets are composed of inner, xed half mold portions, and outer swingable half mold portions, and in which is included novel means for swinging the outer can bodies from said shelf-like pocket and swing them into position against mold portions.

Another object of the invention is to provide a machine of the character stated in which the reciprocable anging heads each have a notch for receiving end extremities of the 'interlocking hook portions of the side seams, thereby to ilange the can body ends in close to and Without interference by said end extremities,. and in which the can body feeding like pocket and the outer half mold pocket portions have provision, for` assuring alignment of the container body side seams with said fianging head notches.

Another object of the the inner, xed half invention is to provide aP machine of the character stated in which each;

means including the shelftherewith a swingable member effective to assist in controlling the movementl of the container bodies into the fixed, inner half mold portions and for stripping the container bodies from said invention, a fragment of a body maker also being shown.

In the example of embodiment of the invention herein illustrated a fragment of the delivery end of a standard form of body maker is indicated at 5, and it is beneath the arch 6 of this unit that the container bodies to be flanged in the anging machine herein disclosed are finally shaped and have their interlocking seam hooks brought together and bumped in completion of the solderless side seam.

The anging machine proper includes a base frame'1 having an end extension 8 at its front end, or the end toward which container bodies are fed, two spaced lateral extensions 9 at its right hand side, and a lateral extension I0 at its left side. See Figures l, 2 and 4 of the drawings. Between the spaced extensions 9 the base frame includes a downwardly and outwardly inclined portion II which serves as a delivery chute for flanged container bodies and supports a plurality of spaced chute rails I2 and parallel spaced confining side walls I3.

At its rear end the machine includes a frame standard |4 having a gear housing portion I5 equipped with a removable cover plate I5. The irregular opening I1 in the front wall of the housing portion is closed by a plate cam I8 having an actuator groove I9 formed therein, and a hub portion 20 to which a grooved cam head 2| is stationarily fixed as at 22. See Figure 3. The cam head 2| is equipped with an actuator groove 23,'and the purpose of the cam grooves I9 and 23 will become apparent as this description of the invention progresses.

The fixed cam head 2| forms a bearing, as at 24, for one end of a main rotary shaft 25, the other end of the shaft having bearing, as at 2S, in a bearing sleeve 21. See Figure 3. The bearing sleeve 21 has a plate cam 28 fixed thereon, as at 29, and is spline-mounted, as at 30, in a bearing standard 3| fixed upon the frame extension 8. The plate cam 28 is equipped with an actuator groove 32, and the sleeve 21 is secured, as at 33, to a. cam head 34 which surrounds the shaft 25 and is equipped with an actuator groove 35. The purposes of the cam grooves 32 and 35 will later become apparent.

The sleeve 21 is externally threaded, as at 35, and is engaged by an internally threaded hand wheel 31 held captive by connection at 38 with the frame standard 3|. Thus by rotating the hand wheel 31, the sleeve 21, the plate cam 2S and the cam 34 may be moved longitudinally on the shaft 25.

Intermediately of the cams 2| and 34 the shaft 25 carries two rotors 39 disposed in longitudinally spaced relation, as shown in Figure 3, and mounted for rotation with said shaft. These rotors are bridged over by a pair of bridge frame pieces which are disposed in spaced parallel relation and are mounted on the frame extensions 9 and I0 in the manner best illustrated in Figures 1 to 4 of the drawings.

A vertical standard portion 4I extends upwardly from the frame standard I4 and in this, the bridge piece 40, and the standard 3|, a frame rod 42 is mounted. See Figures 1 to 4.

A large gear 43 is keyed on the shaft 25 within the housing portion I5 and is driven by an intermediate gear 44 also mounted within the housing portion I5, on a stud shaft 45, and which is in turn driven by a small gear |26 xed to rotate with a large gear 41 mounted on a stud shaft Lit. The large gear 41, like the gears 46 and (iii, is mounted in the housing portion I5, and it meshes with and is driven by a driver gear 49 mounted in an extension 50 of the main gear housing and carried on an extension of the main drive shaft 5I of the body maker which feeds containers to be flanged into the improved fianging machine. See Figures 2 and 5.

In practice, the horn about which the container bodies are formed, and against which the solderless lock and lap side seams thereof are bumped, is extended, as at 52, to a point at which can bodies are to be delivered for being flanged in the improved 'flanging machine. This extended free end of the horn is supported on a roller 59 carried on a horizontal arm of a bell crank lever 54, said roller being capable of a limited amount of downward movement to permit passage of container bodies under the control of movement limiting screws 55 and 56, said roller being constantly urged against the horn by a tension spring 51.

The horn extension 52 is grooved along its under surface, as at 58, and has a rail 59 secured in said groove, as at 60. The rail is grooved, as at. 6|, to receive the inwardly directed side seam extension formed by the interlocking hooks of the side seam, therebyto definitely retain a given position of the container bodies as they are fed along the horn. The horn extension includes the usual slide rails or spacers 62 and a reciprocable feed bar 63 having yieldably projecting feed fingers 64 effective tointermlttefitly feed container bodies successive, definite distances along the horn. If desired, additional lkeeper detente 65 may be provided for intercepting containers fed the successive steps by the finger bar 68 and overcome any tendency of the container bodies to move back with the nger bar during its movements of retraction.

As each container body is fed off the end of the horn extension it is received in a half cylindrical rest pocket 66 having a bracket extension 61 which is secured, as at 68, on the machine framing. The stationary rest pocket 66 includes an 'abutment wall portion 69 which confines containers against endwise displacement and which is spaced, as at 10, from the main body of the pocket a distance sufllcient to permit passage of movable, container engaging half mold portions at either side of and closely adjacent to the end extremities of the rest pocket 66 in the manner best illustrated in Figure 8 of the drawings. It will be observed that the main body portion of the rest pocket 66 is of a length for permitting the end extremities of containers 1| to project beyond the ends of the pocket in the manner indicated at 12. The rest pocket 66 is provided with an aligning rib 13 which is engageable in the groove 14 disposed at one side of the interlocked seam hooks 15 in the manner best illustrated in Figure 9 of the drawings. The groove 14 is formed in a well known manner during the bumping of the side seam and results from the provision of a seam locking rib effective to prevent disruption of the interlocked relation of the hooks of the solderless side seams 15 as a result of stresses set up in shipment or handling of the finished containers. By engagement of the aligning rib 13 in the seam grooves 14 as the container bodies are individually delivered into the rest pocket 66, the alignment of the side seams attained by engagement of the seams with the horn groove 6|, ,is effectively maintained. The solderless side seam 15 preferably, but not necessarily, includes a packing insert 18 of paper or other non-metallic material.

Each rotor 39 includes a sleeve surrounding the shaft 25 from which webs 11 extend and carry four sets of axially aligned cylindrical bearings 18. See Figures 1, 3 and 'I of the drawings.

Each bearing 18 supports a longitudinally recip,

rocable plunger or piston 1l which has a non- 75 circular portion within the bearing and engaged by a removably mounted key-piece 8| effective to prevent rotation of the plunger wit in the bearing. The plungers' 19 of each opposed set extend from the inner ends of the" bearings 18 and are equipped with heads 82 to each of which a Hanging head 83 is secured, as at 84, against a spacer shim ring 85 of selected length. At its outer end, each plunger 19 carries a roll 86 engageable in the adjacent cam groove 23 or 35, and the cam grooves are effective to cause the plunger of each set to move inwardly toward leach other or outwardly away from each other during the cycle of operation ofthe machine designed to effect a proper flanging of the can bodies.

Each bearing 18 at the end of the machine at which the plate cam I8 is mounted is equipped vwith two spaced bearing sleeve extensions 81 in which a shaft 88 is rockably mounted. See Figure '1. Each such shaft has a crank 89 ailixed thereto which is equipped with a roller 90 engageable in the actuator groove 9 of the adjacent cam I8, and is held against longitudinal movement in the bearing extensions 81 by said crank and a stop collar 9| x'edthereon. Each shaft 88 has two half circular, outer halfV mold memmold members 92 are movable by the cam and crank connections ner halfY mold equipments 92 and 94 are moved into cooperative relation, as indicated at the right in Figure 4 of the and 94, the free ends of the members 92 interlock at 96 with the disks 95 in the manner best illustrated in Figures 4, 6 and 13 of the drawings.

Between each pair of outer half mold members 92, two sleeves`91 rockably surround the shaft 88, said sleeves being disposed in end abutment and removably interlocked, as at 98. See Figures 7 and 8 of the drawings. Each sleeve 91 carries a container confining and stripping finger 99 and each of the outerv half mold members 92 is rec essed, as at |00, to partially clear the adjacent stripper finger and permit each stripper finger and outer half mold member 99 and 92 to pass at one end or the other of said rest pocket 66 in the manner illustrated in Figure 8. Each shaft 88 includes an axial borel'l in the inner end thereof for receiving the inner end of a rock shaft extending through' a longitudinal slot |04 in the surrounding portion of the shaft 88, thereby to permit a degree of relative movement of the mounted in a bearing extension |01 the cranks |09 and stop collars- In order to securely hold the outer half mold members 92 against the inner half mold equipments 94 during flanging operations, each of the outer half mold members 92 carries a roller III which is engageable with a holddown track II2. The holddown tracks are mounted on the frame rod l2 and on another frame rod II3 disposed at the side of the machine and which passes through the bridge pieces 40. See Figures 3, 4 and 6. The holddown tracks start at the rod 42 and terminate at II4 just beneath the rod II3.

A solderless side seam equipped container, such as are to be flanged in the improved machine herein disclosed, is described in detail in the U. S. Letters Patent 2,171,711, issued to Plumb, et al., Sept. 5, 1939. In this form of container the lapped portions of the side seam are not as long as in standard forms of lock and lap seam equipped containers, and these entire lapped portions are rolled into the side seam so as to bind the lapped portions against the included packing strip and against the end extremities of the locked portions of the side seam thereby to assure against leakage at the ends of the side seams. The flanging of container bodies thus formed heretofore presented problems because it was impossible to project flanging heads a proper distance into the container ends because of engagement with the extremities of the locked portion of the seams, nor was it possible to effect the flanging operation without improperly spreading and disrupting the container body seams at the lapped portions. These problems have been avoided in the present machine by provision of the peculiar arrangement of half mold, can end supporting portions, and by providing each anging head 83 with a notch I I5 in which to receive an extremity of the interlocked side seam portion of a container being flanged. By reason of the provision of the guiding groove 6I along the bottom of the horn extension 52, the seam position retaining rib I3 on the rest pocket 66, and the provision of seam position retaining ribs IIS on the outer half mold portions 92, proper alignment of the end extremities of each container body side seam with the notches I I in the flanger heads 83 adapted to engage in and effect the flanging of the ends of that particular container is assured.

When the machine is in operation, continuous rotation is imparted to the rotor comprised by the shaft 25, the rotor parts 39 and the plungers 19 reciprocable in the bearings thereof, and the inner and outer half mold members, through the 5 medium of the transmission gearing best illustrated in Figures 2 and 5 of the drawings, the power being `applied from the main shaft extension 5I from the body maker. As the rotor rotates relatively to the stationary cams 2|, 34, I8 and 28, the plungers 19 are reciprocated in the bearings 'IB so as to alternately move toward and from each other, and the outer half molds are alternately swung away from their cooperative relation with the inner half molds, as indicated at the central lower and left portions of Figure 4, and then again to the cooperative relation with said inner mold portions as indicated at the right inisaid Figure 4. The cam grooves 23 and I9, and 35 and 32 are so co-related that the ilanging heads are moved into engagement with the half mold sections while they are in the container/end embracing and confining cooperative relation illustrated at the right in Figure 4 for the purpose of Hanging the short length of can body projecting at each end beyond said half mold members.

The container bodies fed step by step along the horn extension 52 by the feed bar 63 are delivered one by one onto the rest pocket 66 in the manner illustrated in Figures 6 and 8 of the drawings. Each container body thus placed on the rest pocket is picked up by the next advancing, outwardly swung outer half mold in the manner illustrated at the left in Figure 6 of `the drawings, and it will be observed that at the time each container is picked up the fingers 99 overlie the same suiciently to prevent displacement of the container body from the outer half mold. As the rotor continues its upward movement, like portions of the cam grooves I9 and 32 will cause the outer half molds 92 and the fingers 39 to move together, the outer half molds 92 serving to move the container body into the cooperating inner mold recesses 94 andthe fingers 99 serving to control this movement of the container body and prevent said container body moving freely away from the outer half mold members 92. As the unit reaches the top of its path of travel, as viewed in Figure 6, the rollers III of the unit will engage the holddown tracks I I2 and secure the cooperative relation of the inner and outer half mold equipments, the interengaging notches 96 also serving to lock the free ends of the members 92 against displacement in the direction of the axis of the rotor. While the half mold members are thus held securely about the end portions of the container body the cam grooves 23 and 35 force the plungers 'i9 toward each other and the flanging heads engage in and flange the ends of the container body. After the container body has been thus ilanged, the rollers IH roll olf the ends IM of the holddown tracks II2 and free the half molds to swing to the container discharging position illustrated at -the bottom in Figure 6. The cam tracks I9 and 32 are so shaped that the fingers S3 follow the movement of the outer half molds 92 to the container body discharging position so as to act as stripper members in the manner illustrated in Figure 6, but it Will observed by reference to this figure that the cam track permits the half mold members 92 to open before the cam track 32 causes the fingers 99 to start their outward or container stripping movement, and obviously movement of the half mold members 92 away from the cooperating half mold recesses 9a does not start until the respective rollers III leave contact with the discharge end H4 of the holddown tracks II2.

While passing from the flanged container body discharging position illustrated at the bottom of Figure 6, each outer half mold member is retained in the extended position illustrated until it reaches the container pick up position illustrated at the left in said Figure 6. While moving to the pick up position the position controlling cam groove moves the associated finger equipment 99 inwardly with respect to the half mold members 92 so as to clear a container resting on the rest pocket G6, and then again to the position illustrated at the left in Figure 6 to overlie the container body after it is picked up by the half mold 92 and prevent displacement of the container body therefrom. While passing from the position illustrated at the left in Figure 6, the half mold members 92 are moved into cooperative relation with the inner mold recesses 94, and after the complete embracement and confinement of the container body to be flanged is thus completed, the roller III passes under the holddown -It is to be assumed, of

' down trac justment t ereof along the rod 42.

' and assure against leakages at the ends of the seams despite the fact that said seams are not secured by soldering. As previously described, the engagement of the side seam extremities in the flanging head notches l I is assured by maintaining constant control of the positioning of the side seams by engagement thereof with the groove 8| along the bottom of the horn extension, the aligning rib 13 on the rest pocket 66, and the aligning ribs I I8 on the outer half mold members 92 which line up with said flanging head notches.

As previously stated, shim rings 35 of different lengths can be interposed between the plungers 19 and the flanging heads 83, thereby to vary the spaced relation of said heads and adapt the machine for hanging operations on containers of varied length. Also, by turning the hand wheel 31, the cams 2B and 34 can be moved longitudinally on the shaft 25 as an additional means of varying the spaced relation of 'the flanging heads. course, that the rotor portion adjacent the cam 34 also will be moved longitudinally on the shaft 25 with which it rotates and that the spaced relation of the holdi H2 will be suitably altered by 'ad- `It is of course to be understood that the details of' structure and arrangement of parts may be variously changed a'nd modifled withoutdei parting from the spirit and scope of my invention.
